Abstract: SCRUBBING METHOD AND APPARATUS USING       VIBRATING TERRY CLOTH                ABSTRACT OF THE DISCLOSURE         A method and machine for cleaning carpet, and the like floor surfaces is disclosed which includes a vibrating type machine having a vibrating drive plate which carries a layer of plastic barbed bristles facing the carpet.  A piece of terry cloth is placed between the bristles and the carpet and the barbed bristles hook the loops of the terry cloth for attachment and massage the carpet through the terry cloth to impart a scrubbing motion to the cloth.  Use of short-loop terry cloth having terry loops of about 1/4 of an inch or less effectively results in transmission of machine motion for effective machine movement and cleaning.  The method contemplates moistening a piece of terry cloth with a cleaning solution so that soil is removed and absorbed by the terry cloth without any significant wetting of the carpet after which the terry cloth may be removed from the barbed bristles and utilized on a reverse side or replaced.  Removal of shampoo and soil is built into the method and machine in an effective manner.

Abstract: Non-Contacting Multi-Function Sensor Arrangement Abstract Apparatus for measuring the amount of phase shift between first and second rotating shafts and/or the amount of limited movement of a third shaft from a reference position.  First and second magnetically sensible members move through circular paths at speeds proportional to the speeds of the first and second shafts, respectively, and first and second signals  are generated by first and second magnetic sensors fixed adjacent the respective paths of the sensible members. A third signal is generated by a third magnetic sensor , which is movable along the path of the second sensible member in response to movement of the third shaft.  Clock pulses from clock are counted between successive second and first signals and are counted between successive second and third signals to provide digital information proportional to the phase shift between the first and second shafts and movement of the third shaft.

Abstract: TOUCH CONTROL ARRANGEMENT FOR DATA ENTRY     ABSTRACT OF THE DISCLOSURE           A touch control arrangement is disclosed which employs a touch panel comprising a plurality of touch keys and a network of electrically connected capacitive elements; an oscillator which incorporates the network of capacitive elements in its timing circuit; and a microprocessor coupled to the output of the oscillator and operative to control various appliance operating components as determined by the frequency of the oscil-lator output signal.  The keys of the touch panel are operatively coupled to the network of capacitive el-ements such that actuation of a key or pad by the user changes the equivalent capacitance of the timing circuit causing the oscillator to generate a control signal at the frequency associated with the actuated key.         In one embodiment, the touch control arrange-ment employs a tactile touch keyboard arrangement in which the user actuates a key by depressing the key, which changes the equivalent capacitance of the network to the value corresponding to the actuated key by shunt-ing a predetermined portion of the capacitive network.          In another emobdiment, the touch control arrangement employs a capacitive touch pad array in which body capacitance of the user when touching a key changes the equivalent capacitance of the capacitive network to the value associated with the pad that is touched.

Abstract: HEAVILY PERFUMED PARTICLES AND DETERGENT COMPOSITIONS          David D. Whyte ABSTRACT OF THE DISCLOSURE     Heavily perfumed detergent compositions having both immediate and long lasting perfume emitting properties are prepared by a process in which perfume is emulsified in a water solution of water-soluble polymer, and the emulsion is mixed with a powdered hydratable material, in such a ratio that all of the water in the emulsion can be bound in the resulting nydrate, eliminating a separate drying step. The result is a dry, free flowing granular material which can be readily dry mixed into fully formulated detergent compositions.  The perfume is retained in the polymeric matrix and is released at the point of product use when contacted with water.

Abstract: Abstract of the Disclosure A video disc player designed to play video disc records having either non compressed monophonic wide band audio signals or video disc records having compressed stereophonic limited band audio signals recorded thereon. The player includes expander circuitry which may be selectively operated as a time invariant amplifier in the absence of stereo audio signals and as an amplifier with a time varying transfer function for expanding the stereo signals. The expander circuit operating mode is controlled by a circuit which detects the presence of a second or stereo sound carrier in the signal recovered from the record being played. Concurrently with the amplifier being rendered time invariant during the playback of monophonic records, electronic filter circuitry is switched into the amplifier circuitry to reduce the monophonic audio bandwidth and effectively increase the resultant audio signal-to-noise ratio.

Abstract: ABSTRACT         Standby power supplies for key telephone systems are known which derive 24 VDC, for charging a battery, from commercial power mains, e.g. 117 VAC, and also derive 10 volt AC for energizing lamps, bells, and the like in the telephone system.          These systems are bulky and expensive.  The present invention, which is smaller and less expensive, is normally powered by 10 volt AC from the key telephone system and this 10 volt AC is fed to a charger which trickle charges the 24 V battery supply.  In the event of a commercial power interruption the charger is automatically disconnected from the 10 volt AC and power is derived from the battery supply which drives a 10 volt AC inverter to power the lamps, etc. in the key system.

Abstract: REDUCTION OF STRENGTH LOSS   DURING FIBER PROCESSING        Abstract Glass fiber strength is improved by removal or avoidance of water derived species within the fiber such as result from exposure of coated or uncoated fiber to ordinary air.  Of particular significance is retention of greater strength during a step following thermal processing such as during splicing.  Strength improvements result from a procedure, e.g., protection of fiber to avoid exposure to water-bearing ambient or use of medium which chemically alters such water-derived species in the fiber.

Abstract: Abstract Feed Forward AC Voltage Regulator Employing Step-Up, Step-Down Transformer and Analog and Digital Control Circuitry A feed forward AC voltage regulator utilizes a step-up, step-down transformer to apply adjust-ment voltages to an unregulated AC line.  Analog circuitry periodically samples the unregulated AC line input and compares it with a scaled represen-tation of the desired line voltage.  Digital circuitry converts the information from the analog sampling and comparison to an instruction command which activates an appropriate solid state switch associated with a tap on a multitap transformer connected to the regulated AC output line.  The taps are successively located on the multitap transformer to provide selectable adjustment voltages of various values.  The switched-in adjustment voltage is provided the proper polarity and applied to the primary of the step-up, step-down transformer, thereby applying to the secondary the adjustment voltage needed to move the regulated AC output line to the desired level.
